Entanglement and extreme spin squeezing of unpolarized states
(IOP Publishing, 2017-01-20)We present criteria to detect the depth of entanglement in macroscopic ensembles of spin-j particles using the variance and second moments of the collective spin components. The class of states detected goes beyond traditional ... -
Number-phase uncertainty relations and bipartite entanglement detection in spin ensembles
(Verein Forderung Open Access Publizierens Quantenwissenschaf, 2023-02)We present a method to detect bipartite entanglement based on number-phase-like uncertainty relations in split spin ensembles. First, we derive an uncertainty relation that plays the role of a number-phase uncertainty for ... -
Spin squeezing, macrorealism and the heisenberg uncertainty principle
(2015-10-09)En paralelo con el desarrollo de un formalismo matemáticobien definido para la teoría cuántica [19, 48, 175], se abrióun debate sobre el sorprendente contraste entre los ¿misteriosos¿fenómenos cuánticos (incompatibilidad ...
